MR8740T – Memory HiCorder


Max. 108 Analog Channels, Reduce Inspection Data Transfer Time to Zero


MR8740T – Memory HiCorder (1GW memory, main unit only)


The MR8740T (MR8740-50) is rack-mountable data acquisition system that delivers high-speed, multi-channel measurements over maximum of 108 channels. Generate simulated signals and record at the same time using plug-and-play input units, making the waveform recorder ideal for evaluating multi-signal devices such as vehicle electronic control units (ECU).

Key Features

  • Ideal for multipoint inspection of high performance boards such as ECU.
  • 108ch analog to 96ch analog + 48ch logic input.
  • Reduce time required to save to external media to max.1/100 compared with conventional method.
  • 20 MS/s simultaneous sampling on all channels/
  • Safe measurement with all analog inputs isolated.
  • Supports 4K monitor to display multi-channel waveforms without overlapping.
  • Measure 4 channels with 1 unit (4 ch analog Unit U8975, 4 ch DVM Unit U8991).
  • Generate constant voltage, constant current, and simulated resistance (VIR Generator Unit U8794).
Number of input units Max. 27 slots
Number of channels [Using the U8975] Max. 108 ch analog, or 96 ch analog + 48 ch logic (when used in combination with U8975 + 8973)
[Using the 8966] Max. 54 ch analog, or 48 ch analog + 48 ch logic (when used in combination with 8966 + 8973)
*Logic unit 8973 is limited to slots 25 to 27, up to 3 units.
